Earlier quoted context omitted.
Venmo[1] does not have reversibility. Cash does not have reversibility. If users really wanted credit card functionality at the expense of its costs, you could build that as a layer on top, without forcing everybody in the system to use it. And consider, most disputes is not just about the quality of a product. That is handled with regular refunds. Credit card disputes are a lot of times because of fraud or card skim…
We already have that system - debit cards, cash, venmo, apple pay, etc. What does crypto solve other than anonymization of payments?
about the OP’s thread: centralized services like PayPal, Venmo and Stripe can close your account. Nobody can close your private key, even if you are on a L2 for fast payments you can use the escape hatch to withdraw without possibility of censorship.
